Answer 1

There is a space in your command, after -Dfile=!

 mvn install:install-file -Dfile= ~/Downloads/<jar_path> -DgroupId=<groupId> -DartifactId=<artifactId> -Dversion=<version> -Dpackaging=jar -DgeneratePom=false

try

 mvn install:install-file -Dfile=~/Downloads/<jar_path> -DgroupId=<groupId> -DartifactId=<artifactId> -Dversion=<version> -Dpackaging=jar -DgeneratePom=false
